Title: Crankshaft for V=8 IC vehicle engine - has inner web balance weights in plane symmetrical to crank throws
Inventor: SPEIER WOLFGANG DIPL ING
IPC: F16F15/28
Filed: 1977-12-21
Abstract: The crankshaft is for an 8-cylinder internal-combustion engine with two rows of cylinders at 90 deg to each other, having four throws in all, each serving a pair of cylinders in opposite rows. The two outer throws extend in opposite directions in the one plane and the two others in the second one at right angles to it. A balance weight is fixed to each web of each throw and to the outer webs of each inner throw. The balance weight (11, 12) on the outermost web (7, 8) of each outer throw (5, 6) lies in the plane of the throw concerned. Those (17, 18) on the outer throw inner webs (13, 14) and (29, 30) on the inner throw (22, 23) outer webs (24, 25) adjacent to them lie in a common plane (19-19) contg. the crankshaft axis (3-3) and symmetrical in relation to the planes of the throws (4-4, 21-21).

Title: Valve bag filling machine - includes rotor on which is mounted filler nozzle and transfer arm carrying gripper
Inventor: KNORR GUENTER DIPL ING
IPC: B65B43/26
Filed: 1978-05-24
Abstract: The valve bag filling machine has a rotor (2) to which is attached one or more arms (7), each carrying a gripper (13) which can swing about an axis (12). A magazine for holding ready bags (15) to be gripped is mounted in a fixed position relative to the rotor. A cam (22) is mounted adjacent the magazine to engage a lever (23) coupled to the gripper which is biased into a leading position relative to the rotation of the rotor, so that, as the lever engages the cam the gripper swings towards a bag in the magazine, thus reducing the gripper's velocity relative to the bag to a minimum. As the bag is gripped the cam causes the gripper to move slightly in a direction opposite to the direction of rotation of the rotor. The lever then disengages from the cam and a locking mechanism locks the gripper in a predetermined position.

Title: Handlebar clamp for bicycle - has two part threaded sections allowing separate clamping of handle bar and forks
Inventor: GRETZINGER HANS
IPC: B62K21/18
Filed: 1978-06-30

Title: Silicon deposition from vapour phase - with substrate temp. periodically lowered and raised between optimum and minimum
Inventor: KASPER ANDREAS
IPC: C01B33/035
Filed: 1978-07-19
Abstract: Silicon in fine crystalline form is deposited from the vapour phase on a substrate which is heated by the passage of current. At a set molar ratio of the reactant gas and a chosen gas flow rate, the starting temp. of the substrate is set to 1100 degrees C. This temp. is lowered in accordance with a set programme to a min., followed by raising it to 1100 degrees C. This is repeated several times with or without holding it at 1100 degrees C. This achieves during the mfr. of polycrystalline Si rods a good si halogen yield, combined with a good fine-crystalline surface of the Si, and not one or the other as in conventional procedures.

Title: Three-lift control system - has switching module for each lift, comprising free lift search circuit with direction decision switch acting on module memories
Inventor: SAMARIN IVAN DIPL ING
IPC: B66B1/18
Filed: 1978-12-23
Abstract: The lift control and indicator system for a large number of floors, is used to operate three lifts. The three circuits are each controlled by a module which determines which direction a call signal requires, and stores the calls in a memory system. This is carried out during the middle of travel of the next lift or in the opposite direction to the travel of the most remote lift. In the event of the signal not being answered the signal is reprocessed and allocates to the next lift. The system uses at least a minimum combination of AND and OR-gates to pass signals corresponding to test for an approaching signal, test for a receeding signal and test pulse. Each floor has its own module, these being grouped in available floor numbers. Each contains switching elements which cancel a call signal, if it has not been utilised. These modules and their groups contain chains of logic elements which enable new selection of this call signal and its allocation, when its previous cancelling has taken place.

Title: Glass-fibre reinforced resin masts - mfd. using heated and cooled conical core in polygonal conical mould
Inventor: GILBERT CHRISTIAN
IPC: B29C70/54
Filed: 1979-03-22
Abstract: Masts, specially for use as telephone or street lamp poles, are made of glass fibre reinforced plastic by casting the resin in a conical mould with a conical core so that the stretched glass fibre strands are entirely embedded. The glass fibre roving are kept at a tension. The mould is fitted with heating and cooling facilities. This process facilitates the ejection of the core after completion.
